Reliability in Wireless Sensor Networks Using Soft Sensing

The nodes in wireless sensor networks are prone to failure due to fading energy. The wireless sensor network applications that require continuous data-supply, suffer due to energy limitation of the sensor nodes. A technique based on soft- sensing principles is employed in this paper to assure the availability of data to these applications, where there is no compromise on data acquisition due to node failure. The results generated through simulations justify that the proposed methodology could be used effectively in such systems where the reliability is high priority.
